BEDSTEAD-FASTENING.

Specification of Letters Patent No. 5,887, dated December 4, 1847.

T0 all wiz-0m t may concern Be it known that I, HARVEY B. NASH, ofKingsbury, in the county of Washington and State of New York, haveinvented a new and Improved Method of Joining and Putting Together Postsand Rails of Bedsteads; and I do hereby declare that the following isa-full and exact description thereof.

The nature of my invention and improvement consists in uniting the postsand rails of bedsteads, by means of mortised cylinders made with stopsor projections and secured in the posts; and sliding tenon with T headslet into the ends of the rails where they are made fast by an eccentricpin-the head being inserted through the mortise 1n the xed cylinder. l

To enable others skilled in the -art to make and use my invention Ishall proceed to describe its construction and operation. I construct mybedstead posts and also the rails of the bedstead in any of the knownforms proper for using bed cords or slats; but in order to render thejoints perfectly secure and permanent and prevent the same from becomingloose from wear or other cause and to enable the same to be drawntogether perfectly tight without the application of much labor; and alsoto be put up and taken down with facility and despatch I secure thejoints in the following manner.

Figure 1 is a perspective view of the posts and rails secured togetherby the improved fastenings. Fig. 2 is a perspective view of the tenonand cylinder connected together and detached from the posts and rails.Fig. 3 is a front and backJ elevation of the cylinder. Fig. 4 is a planand side elevation of the tenon. Fig. 5 is a plan and side elevation ofthe eccentric pin. Fig. 6 is a plan and side elevation of the wrench forturning the eccentric pin. Fig. 7 is a tenon with a T head fixed to itby a screw. Fig. 8 1s 'a perspective view of a tenon with a cylindricalhead let into the post. Fig. 9 1s a perspective View of a tenon with adovetailed head let into the post. Fig. 10 is a perspective view of atenon with rounds and points let into the post.

I use a hollow cast iron cylinder let into the posts and secured firmlytherein into which a cast iron tenon let into the rail, is inserted,being drawn into the rail in order to close the joint by turning aneccentric pin which passes verticaly through the rail and shank of thetenon.

The cylinder A Figs. l, 2, 3, is cast withv an oblong mortise B Figs. 2and 3 through t-he same to admit the tenon C Figs. 2, 4, 7 and has twoshoulders D D Fig. 3 against which the T head T of the tenon Fig. 4

rests when turned a quarter of a revolution,

one of said shoulders D extending from near o-ne end of the cylinder andthe other D from the other end thereof. A projection E E Fig. 2 is caston the ends of the front of the cylinder next the rail against which theshoulder F of the cast tenon of the rail rests as represented at F inFig. 2 in which E E are said projections on the cylinder and F F are theshoulders of the tenon. The tenon is made cylindrical where it extendsbeyond the end of the rail and where it enters the mortise in thecylinder. The shank which enters a mortise in the rail is made of anoblong shape and is pierced with an eccentric opening to admit aneccentric pin. The T head of the tenon is either cast with the tenon, oraffixed to it, by means of a screw and is in length nearly equal to thediameter of the cylinder being attached to the cylindrical portion ofthe tenon. The screw is represented at S in Fig. 7.

The tenon is secured in the rail by a cast iron eccentric lever pin Hpassing vertically through a hole in the upper side of said railcorresponding in size and shape with that part of said pin which isimmediately next to the head thereof, thence passing through a smallhole in the said tenon corresponding in size and shape with that part ofsaid pin which passes through the said tenon-thence through a stillsmaller hole in the lower or under side of said rail corresponding insize and shape with the smaller or lower end of said pin. Said eccentriclever pin has a large flat head made to set snugly in a circular recessin the top of said rail when in use. Said pin has a square aperture sunkor cast into the head thereof to receive a corresponding square castiron wrench I Fig. 6 made to fit into the same; said pin is of anunequal size in its different portions or degrees of length and is of anirregular or eccentric shape in the middle and is so made in connectionwith said hole in said tenon through which it passes that when the sameis turned by the aid of said wrench in said hole in said tenon, thatpart thereof which comes in contact with said tenon in passing throughsaid tenon, operates with a lever power against said' sliding tenon insuch way as to draw the said joints of the bedsteads perfectly tighttogether and when so drawn together said pin will hold the jointperfectly tight without any other fastening.

I sometimes make the sliding tenon with a cylindrical head fiXedpermanently in the posts as represented at Fig. 8, and sometimes wit-h adovetailed head Fig. 9 let into the post as represented at J, K, andsometimes with rounds and points as shown at L Fig. 10. Said tenon beingdrawn into the mortises in the rails by eccentric pins in the mannerbefore described.

The advantage derived from this mode of fastening is due to thecombination of what is considered two distinct modes of fastening. Thetenon and mort-ise alone or the cylinderA and T head tenon alone wouldrequire the rail to be brought to one exact position before it could betight; but by combining the two it is evident that the rail may be drawnup tight in Various positions, which could not be the case in otherfastenings hitherto known to me.

What I claim as my invention and desire to secure by Letters Patent, is-

The combination of the cylinder A with the sliding tenon C F andeccentric pin H, constructed, arranged, and operated in the manner andfor the purpose described for fastening bedstead joints.
